Investigation of the effects of the Greek extreme wildfires of August 2021 on air quality and spectral solar irradiance

In August 2021, a historic heatwave was recorded in Greece which resulted in extreme wildfire events that strongly affected the air quality over the city of Athens. Saharan dust was also transferred over Greece on certain days of the same period due to the ...

Validation of Spectral Simulation Tools for the Prediction of Indoor Daylight Exposure

Marilyne Andersen, Clotilde Marie A Pierson

A growing area of research focuses on the relationship between ocular light exposure and the non-visual responses. In order to accelerate research on this topic and improve building design, reliable spectral simulation tools are needed. This study aims at ...

Validation of Spectral Simulation Tools for the Prediction of Indoor Electric Light Exposure

Marilyne Andersen, Clotilde Marie A Pierson, Myrta Gkaintatzi-Masouti

As the interest in design applications related to responses to light beyond vision is growing, two simulation tools, ALFA and Lark, have been developed to incorporate spectral characteristics of light in the evaluation of indoor lighting conditions. The sp ...

Visible light plays a significant role during bacterial inactivation by the photo-fenton process, even at sub-critical light intensities

César Pulgarin, Cristina del Socorro Lonfat, Stefanos Giannakis, Rosa Mosteo, David Muzard, Angelica Varon Lopez

The aim of this research is to clarify the contribution of sunlight wavelengths, irradiance and Fe2+/H2O2 during bacterial disinfection by the photo-Fenton process in clear surface waters. We considered different solar spectrum distributions (visible, UVA- ...

Local estimation of the global horizontal irradiance using an all-sky camera

Mario Paolone, Fabrizio Sossan, Enrica Scolari

Localised and high-frequency measurements of the global horizontal irradiance (GHI) are a key information to assess the level of power production of distributed photovoltaic generation. The paper presents a supervised machine learning-based procedure to es ...

An unsupervised method for estimating the global horizontal irradiance from photovoltaic power measurements

Lorenzo Nespoli, Vasco Medici

The precise calculation of solar irradiance is pivotal for forecasting the electric power generated by PV plants. However, on-ground measurements are expensive and are generally not performed for small and medium-sized PV plants. Satellite-based services r ...

Spin waves with large decay length and few 100 nm wavelengths in thin yttrium iron garnet grown at the wafer scale

Dirk Grundler

Using conventional coplanar waveguides (CPWs), we excited spin waves with a wavelength λ down to 310 nm in a 200 nm thin yttrium iron garnet film grown by liquid phase epitaxy. Spin-wave transmission was detected between CPWs that we separated by up to 2 m ...

Sputtering-induced reemergence of the topological surface state in Bi2Se3

Jan Hugo Dil, Stefan Peter Muff, Thorsten Schmitt, Vladimir N. Strocov

We study the fate of the surface states of Bi2Se3 under disorder with strength larger than the bulk gap, caused by neon sputtering and nonmagnetic adsorbates. We find that neon sputtering introduces strong but dilute defects, which can be modeled by a unit ...

Irradiance prediction intervals for PV stochastic generation in microgrid applications

Mario Paolone, Fabrizio Sossan, Enrica Scolari

The increasing interest in integrating volatile resources into microgrids implies the necessity of quantifying the uncertainty of photovoltaic (PV) production using dedicated probabilistic forecast techniques. The work presents a novel method to construct ...
